The proximate composition and digestible nutrients of roughage grown at Sumiyoshi livestock breeding station were studied using samples of green forage, dry forage, silgae and roots which were collected twice a month from a ration fed to dairy cows from 1977-1979. Proximate analyses for crude protein, crude fat, crude fiber and crude ash were conducted according to the Japanese official testing procedures, and digestible nutrients, DCP [digestible crude protein] and TDN [total digestible nutrients], were calculated using the equations for estimating digestion coefficients and TDN developed by Schneider, et al. (1951). The analytical results for roughage are given. The 2nd values given for each roughage type on chemical composition were cited from the Japanese conventional feed stuffs published in 1975 by the Ministry of Agriculture, Forestry and Fishery. In comparing the values for the main types of roughage grown at Sumiyoshi livestock breeding station and those in the table for chemical composition of Japanese conventional feedstuffs, green bahia grass from Sumiyoshi was higher in DCP and TDN than corn silage. The oats silage also had a higher TDN content. Finger grass hay had a much lower DCP content.
